(2)Unless governments take necessary measures to protect tigers, they may disappear by 2010, the World Wildlife Fund said Thursday.The conservation(保护) group said tiger numbers have decreased(减少) 95 percent in the past century and only 5 000～7 200 tigers still remain in the wild — compared with nearly ten times that many at the start of the century.WWF published an update of their study on Feb. 11, 1999 — Wanted Alive: Tigers in the Wild, marking the end of the Chinese Year of the Tiger.The report states that in spite of the great efforts over the past year, much remains to be done to prevent the tiger from becoming extinct early next century. If governments do not fight against unlawful hunting and get rid of the demand for tiger products the tiger will go to extinction, says WWF.“We cannot relax for one moment if we are to make it certain that tigers will stil l exist in thewild by the next Chinese Year of the Tiger in 2010.” Said Elizabeth Kemt, species conservation information manager at WWF International and one of the authors of the report.Three of the subspecies of tiger—the Bali, Caspian and Javan tigers are extinct. The SouthChina tiger faces the same end as only 20 or 30 are known to remain in the wild, down from 4 000in 1950s.1. This passage tells us that _______.A. WWF is a government organization of ChinaB. there are altogether two Chinese Years of the Tiger: 1999 and 2010C. Elizabeth Kemf didn’t join the authors in writing the report but she agreed to their opinionD. if the twenty to thirty South China tigers were killed, probably no tiger of this kindwould remain in the wild2.
